Note. A slight "grinding noise" may be heard immediately after the engine is started in extremely cold whether conditions (below-20°C): This is due to power steering fluid characteristics in extreme cold conditions and is not an indication of malfunction.
Scheme 9
- Start the engine with the steering wheel in the straight ahead position.
- Measure the play at the circumference of the steering wheel. Standard value Steering wheel free play : 0-30 mm (0-1.1 in.)
- If the play exceeds the standard value, inspect the connection between the steering shaft and steering linkage.
Scheme 10
- Place the front wheel on a turning radius gauge and measure the steering angle. Standard value Wheel angle (Unladen state) Inner wheel : °3737' +/- 1°30' Outer wheel : 31°51'
- If the measured value is not within the standard value, adjust the toe and inspect again.
Scheme 11
Scheme 12
- Disconnect the tie rod and knuckle by using the special tool.
- Move the ball joint stud in a circular motion several times to check for looseness.
- Mount the nuts on the ball joint, and then measure the ball joint starting torque. Standard value 0.5-2.5 N.m (5-25 kg.cm, 0.36-1.78 lb.ft)
- If the starting torque exceeds the upper limit of the standard value, replace the tie rod end.
- Even if the starting torque is below the lower limit of the standard value, check the play of the ball joint and replace if necessary.
Scheme 13
- Position the vehicle on a level surface and place the steering wheel in the straight ahead position.
- Increase the engine speed to 1000 +/- 100 RPM. NOTE: After checking, reset the engine speed to the standard value (idling speed).
- Measure the turning force with a spring scale by turning the steering wheel clockwise and counterclockwise one and a half turns. Standard value Stationary steering effort: 34.3N (3.5 kg, 7.8 lbs)
- Check that there is no sudden change of force while turning the steering wheel.
- If the stationary steering effort is excessive, check and adjust the following points.
- Damage or cracks on the dust cover and tie rod end ball joint.
- Pinion preload of the steering gear box and starting torque of the tie rod end ball joint.
- Starting torque of the ball joint.
